Y 1 f l The invention `consists substantially'in the combination, construction, location andvrelative arrangement of parts, all as will be apparent more fully hereinafter, as shown iny the accompanying drawings, and as finally pointedout in theappended claims.

Referring now rmore ,particularly to the as constructed in accordance with the prineiples of the f present invention includes a substantially elongated tubular memberhlO upon the external surface of which the;` hair iS"`adapted to'be wound;v Itwill be underi@ stood that in-windingithe hairto beheattreated upon-this rod the-hair is first divided ginto y avplurality: of.v strands each of which strands is Subsequently wound in the form of a spiral upona rod: 10 in the manner, :to i90 As most clearly appears in Figu're'V the rear end of the tubular rod 10 is reduced, as

at 11, while the forward -endthereoic is pro,- vided with an enlarged bore,12.. Slipped over the reduced portion 11v of the rod 10 'is aV coil spring 13 the inner extremity of which" bears against the rod portion 11 and the outer extremity of which is turnedwto provide a radially extending lip 14. This spring 13 is so designed thatwhen pressure is aprV plied to thelip 14 in a direction suoli that jthe spring is contracted a binding action is had upon the rod in consequence of vwhich ro-v tation of the spring inY that direction is prevented. ()n the other hand, upon applying a reverse pressure to the lip 14 the convolutions of the spring are expanded thereby permitting free rotation ofthe latter relatively to the rod 10. Thepurpose of this feature VWill be more fully explained hereinafter.

`V Y K operatively associated'` with the tubular rod 10 is a cap member 15l of substantially cylindrical form, the wall of which is pro vided with a' longitudinally extending slot 16. The outerclosed'end of this cap member is knurled, as at 17, while theinner open end thereof is adapted toembrace'the coil Y spring 13 and the adjoining rear end of the rod 10. The rod 10 and member 15y are as sembledrwith the lip 1410i the coil spring projecting through the elongated Aslot 16. It will thus be apparent'that the rod 10 is vaxially movable with respect to the member 15, the extent4 of this movement in one direction being determined by the length' of theslot16.V v l Projected `-throughthe axial bore`18 ofthe rod 10 is a stem o r plunger 19 the 'forward end of which is reversely bent, as .at 20, toV provide a hookedend. The rear end of this stemy or plunger 19 is' *threaded tor threaded engagement, as at 21, with the cap member 15. Embracing the rear portion of .thestem19andi te dit th l d' n Ipose be Ween ec Ose -wardlyralong Vthe rod 10-until the finger 28 end of the capmember 15 and the Y,rear end of the rod 10 isa spiral spring 22v which is operative to maintain the rod in outwardly pressed relation with respect tothe cap member 15.i ThisV outward movement Totu they rod l 10 relative to the-member-l is limitedby virtue of the engagementefected; between 'fthe hooked end ofthefste1n19'and the formally positioned within the enlarged bore 12 of the'rod 10.

Slidably received upon the rod 10 is a knurled collar 23 having a reduced axial extension 24. Formed in this collar 23 is a radially extending slot 25 which extends through the axial extension 24. Seated within this slot 25 is a spring wire 26. This 'wire'26 extends longitudinally of the rod 10. with the opposite ends thereof project ingbeyond the corresponding ends of the collar 231-24. The rear end of the wire 26 is bentand looped, as at 27, to snugly embrace the rod 410. The forward end of the wire is laterally bent,las at28, to provide an areuately shaped linger for engaging a strand of hair to be wound upon the rod. The intermediate portion of thewire 26 kwhich is received within the slot 25 normally tends to flex outwardly and away from the rod 10. Aset screw 29 radially threaded into the slottedportion of the collar 23 bears against the intermediate portion of the wire and forces the'same radially toward the rod 10'. 'It will 'be obvious that by varying` the Vsetting of the screw 29 the plane of the looped end 27 of the wire will be inclined more or less with respect to the axis of the rodY 10 and so effect a varying degree of frictional engagement therewith.A *WithY a proper adjustment of the set screw 29 the looped end of the'wire thus servesY as an effective means for maintaining the 'collarin any desired position without, however, interfering with its free slidable movement along the rod 10.

The manner kof operating and employing the curling rod will now be described. The initialfstep, :as previously.; explained, is to divide "the hair to bel treated into 'a number ot separate strands eachot which is to be separately heat treated and waved. One of these strands of hair, as indicated by the letter S, is inserted within theliooked end 20 ofthe stem 19, this operation being facili tated by shifting the cap member 15 axially 'of ythe rod 10 and against the pressure of the spiral spring 22 totliereby expose the hair engaging hook. The members 10 and 15 are then'perinitted' to reassume the relative positions shown in Figures'l and 3 wherein it will be 'observed that the strand S is' caught 'between the bight end'of the hook and the forward' end-ot the rod 10. The collar member 23 Vis then 'moved forlies substantially in the plane of the forward end ot the rod. rThe'collar'23 and'its associated iinger'28 are then Vrotated in the direc- 'tion/indicated' in Figure 4 such that said fingerl engages thestrand Sat 'a point imniediately adjacent its point of securement to the unit. The'rotation of the collar 23 relativelyftothe'rod 10 is then continucd'simuitaneously as the collar. is moved rearwardly along therod'v'lO. Ylii 'consequence of this operation the strand S will be wound upon the rod l() in the form of a spiral as `clearly appears in Figure 3.

, is produced whereby theV strand is tightly wrapped about the rod.v The hair so `wound upon the rod is then ready to be enveloped within the usual moistened wrapper. It will be observed that the finger 28 is operative as an effective means for-maintaining the free end of the hair against unwrapping, thereby obviating the necessity ofja tying string or other such separate device atthe point X. Similarly, the necessity for a separate tying cord at the point `where the hair tirstengages the curling rod is obviated due to the springpressed hook arrangement. Y

` It will be understood, of course, thatlthe tighteningl action hereinbefore referred to is caused by the relative rotation of the stem 19 and the rod 20, this being effected by firmly holding the rod 2O and rotating the member l l5 in the direction indicated in Figure It will be remembered vthat due to the action of the coil spring 13 the member l5 may be rotated only in the indicated direction, thereby insuring against unintentional or accidental loosening ofthe more or less tightly coiled strand of hair. Y n

It will be yfurther understood that the nger 28 is so shaped and proportioned that the point 30 thereof lies quite close to if not in contacting engagement with the-.external surface of the rod l0. rIhe arcuated portion of theL finger, 28, however, is spaced from said rod surface to an extent sufficient to permit theY free introduction of the -hair strand S therebetween. By means of the set screw 29 it will be apparent that the. pressure .exerted by the finger 28 against the strand of hair 'may be adjusted as desired to thereby compensate for variations inthe thickness of the strand to be treated.

In employing the curling rodv it is not always necessary to use thecollar 23 and its associated finger 28 to effect vthe Winding operation of the hair Vupon the rod.y The sirand S may be woundnpon the rod by hand,

vif desired, whereupon the collar may be shifted into position such that its finger 28 4engages the free end of the strand to hold it in place. The finger 28 in such instance operates solely as a securing element for the free end of the strand of hair. y

It will be understood that the invention has been illustrated in its preferred form and,

` that various changes and modifications thereof may be made from time to timewithout departing from thereal spirit or general principles of the invention as hereinbefore set forth. It is intended therefore to claim the rally' Wound; aj collary rotatably and longitudinally movablej with respect to'- the-rod, said collar having arraxiallyextending slotstherein, and amember rec'eived'within said slo't and extending longitudinally of said rod, onefend l."
